Answer
Urukuta rwa radiyo $ b $ nubugari bwinsinga iringaniye ikoreshwa mu guhuza impeta. Igena impeta yumurongo wa radiyo nubunini bwikibazo ihura nacyo mugihe cyo kwishyiriraho. Imyitozo yo kwishyiriraho $ S_a $ ibarwa nka $ S_a = \ frac {E b imes (D_g - D_f)} {D_f imes (D_g + b)} $, aho $ D_g $ ni diameter ya groove na $ D_f $ ni diameter yubusa. Urukuta runini rwa radiyo yongerera imbaraga imbaraga hamwe na centrifugal stabilite ariko kandi byongera cyane guhangayikishwa no kwaguka (hanze) cyangwa amasezerano (imbere) impeta yo kwishyiriraho. Niba $ b $ ari nini cyane, ibikoresho birashobora kurenga umusaruro wabyo mugihe cyo kwishyiriraho, bikavamo impeta 'irekuye' iticaye neza muri ruhago. Igishushanyo cyiza kiringaniza urukuta rwa radiyo kugirango rutange ibikorwa bihagije bitarenze imipaka yibikoresho.
